Abstract

The invention relates to a microbubble aeration device based on turbulent air mixing, which includes a casing, a driving device, an air intake device, an air intake pipe and a floating body. The casing includes an upper section of the casing and a lower section of the casing. The surface is circular, and the longitudinal section is rectangular; the bottom of the lower shell is open, the cross section is circular, and the longitudinal section is isosceles trapezoidal; the upper shell is connected to the lower shell, and the water enters the aeration device from the bottom of the lower shell. The device of the invention can effectively increase the oxygen content inside the water body, promote the rapid and efficient work of aerobic bacteria inside the water body, accelerate the decomposition of organic matter inside the water body, and prevent water body pollution.

Description

technical field [0001] The invention relates to the fields of environmental protection technology and aquaculture, in particular to a microbubble aeration device based on turbulent air mixing. Background technique [0002] With the development of my country's urbanization process, the urban population is dense, and the original urban sewage works are not perfect, resulting in a large amount of domestic sewage and industrial wastewater being directly discharged into urban rivers, causing serious river pollution, and a large number of black and smelly rivers have seriously affected urban residents. health and cause serious damage to urban water ecology. The management of the black and smelly river has become the top priority in the control of environmental pollution. [0003] Aquaculture is an important part of modern agriculture. With economic and social development and the continuous improvement of people's living standards, the demand for various fish, shrimp and other aqua...
